We recently put in some new ceiling mics and added 2 new 8-inch ceiling speakers to a church that was expanding their building. They don't have anyone there that really knows anything about their audio system and on the day I went down there to hook their amp and soundboard back up, their amp was missing, probably stolen.
I have been trying to find them a replacement amp and want to make sure I get something that will work properly. Part of the problem is the transformers for the existing speakers aren't at the speakers they are at the edge of the church where the roof meets the ceiling. I can see them from a distance in the attic but can't get close enough to get any information off of them, so I'm not 100% sure if they are a 25 Volt or 70 volt system and since they don't have the original amp I can't check and see what it was set to.
The speakers have been wired with the ones on the left and right separately with 4 speakers on each side, including the 2 new ones. The two new ones can be tapped up to 5 watts, the old ones I have no idea.
I'm trying to keep the cost down to around $300. So far I'm looking at getting two of these if I can make sure it is a 70 volt system (The input coming into the amp has an RCA connector):

Any advice or suggestions would be greatly appreciated.
